I like to ride with ankle socks in warm weather. I was using regular cotton ankle length sport socks but prefer wool socks for cycling. These merino wool socks are great for wicking away moisture and helping feet stay dry and cool on hot humid days. I wear a size 13 shoe and the XL chrome merino wool ankle socks stretch to fit my foot, retain their shape after washing, and don't seem to be affected by stretching to fit a bigger foot.
